Problema Solution
One integer is 6 less than another integer. The product of the lesser integer and -7 is 42 more than the greater integer. What are the integers?
Answer provided by our tutors
Let integers are x and y, with y being the lesser integer
y = x - 6
x = -7y + 42
substituting for y into equation 2:
x = -7(x-6) + 42
x = -7x+42 + 42
8x=84
x=84/8 = 10.5
so x can not actually be an integer, x=10.5, y=4.5
